Abstract：In order to explore the eco-hydrological processes of Robinia pseudoacacia artificial forest on the Loess Plateau of West Shanxi Province and its mechanism, in this paper, Revised Gash canopy interception model was applied to simulate the canopy interception amount based on the rainfall data and weather information of 19 events, and forest structure data from July to October in 2007 and 2008. Results showed that the canopy storage capacity and the stem storage capacity of Robinia pseudoacacia artificial forest was 0.55mm and 0.1091mm. The amount of rainfall needed to saturate the canopy was 0.75mm, The amount of rainfall needed to saturate the stem was 8.70mm. Revised Gash model could better simulate accumulative amount of canopy interception of Robinia pseudoacacia artificial forest on the Loess Plateau. The minimum of relative error of accumulative amount of canopy interception was 0.76%, the maximum was 12.60%, and the average was 6.40%. The simulated values of accumulative amount of canopy interception was less than the measured value, and the rate of canopy interception is 2.64% lower than the measured values.
